IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 164,789, dated June2.2, 1875 appl cation filed March 13, 1875.

" and State of Illinois, have invented certain new and usefulImprovements in Combined Cooking, Heating, and Air-Girculatin g Stoves;

and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings and to the letters of reference marked thereon,which form a part of this specification.

My invention consists, first, in the constructiori and arrangement ofthe hot-air lines, so that they may be used not only for heating butalso for ventilating purposes; second, in so arranging said fines thattwo different rooms may be heated or ventilated alternately and, third,in so constructing and arranging the cooking-chamber that it shall-besurrounded on the sides and top by the hot air and products ofcombustion, all as hereinafter more fully shown and described.

On the drawing, Figure 1 represents a vertical section of my improvedstove; Fig. 2 is a horizontal section, in the plane indicated by theline 00 m in Fig. l and Fig. 3 is a horizontal section of the top partof my improved stove, in the plane indicated by the line y y in Fig. 1.

Similar letters of reference indicate corresponding parts in all thefigures".

A is the magazine, or fire-chamber, which is provided with a door, a, infront, by which the draft is regulated, and is surrounded, on the sidesand back, by a closely-fitting screen, N, by which the intermediateair-chamber M is formed. It will be observed that this airchambersurrounds the magazine, where the combustion takes place on all sides,except the front side, where the door is. Air is admitted into theair-chamber M from the receiving-chamber W, located under the bottom ofthe magazine,- through an opening, m, back of the magazine. From M theair ascends,

through the openings 0 and 19, (see Fig. 2,) up into an air-chamberwhich surrounds the cooking-chamber Q on the sides, and then passes upthrough the triangular hot air flue T, from which it is emitted out intothe room where the stove is placed through the valve or register U,which is operated by turning the vase on the top of the stove. Themagazine A is supplied with fuel through a door, B, opening into thecookin g-chamber Q, by removing a'plate or cover, denoted by c, which isreplaced when the magazine is full. The chamber Q is provided with oneor more potholes in the bottom-plate, into which pots, pans, or kettlesmay be placed, and the door Bmay be left open or closed at will. Theproducts of combustion (smoke, &c.,) pass through the flue D up into theflue S, back of the cooking-chamber, and then up into the fine E. Thispartofmyimproved stove is constructed by inserting three metallic platesvertically through the cylindrical top, thus forming three finessurrounding the central triangular airflue as shown in Fig. 3. Inthisfigure, drepresents the outside casing or cylindrical body of the stove.b b b are the plates, inserted vertically through the body. E, F, and Gare the smoke-fines, and T is the central triangular airline, which issurrounded on all sides by the heated plates b b and b From Sthe smokepasses up into the flue E, then through an opening in the top of theplate I) (at so) into the flue F, then through an opening in the bottomof plate b (at'y) into the flue G, and then up through that flue and outintothc smoke-chamber on the top of the stove. By

this arrangement the heat carried ofl in the products of combustion isutilized for heating the air in T, besides warming the surroundingoutside cylinder; and no heat is lost in heating up surface or partsthat do not come in direct contact with the air to be heated. The smoke,after passing up through G, emerges out into the smoke-chamber I, and

then passes out through the stovepipe K into the chimney.

1 have already stated that the air to be heated is taken from thereceiving-chamber W, under the ash-pit b. It finds its way into thisreservoir through three different channels. In the first place, if it isdesired to heat the air of the room in which the stove is placed withoutintroducing new air from without, the valve L (see Fig. 1) is opened,and the valves 3 and v (the latter in another room) are closed,

,FFIGE.

The cold air in the room, which is alwaysnear the floor, enters W by L,then passes through the hot-air chamber M, as already described; then upand round the chamber Q, by way of the openings 0 and 19 (Fig. 2,) thenup through the triangular flue T, and again out into the room through U.

When the room has been heated sufiiciently,

. and itis desired to heat the neighboring room,

outside enters the reservoir W. After being I heated, this air maybe'let outin either room,

by opening either at U or at or or the-valves on the top may be soregulated that it may be emitted, simultaneously into bothrooms.Suitable arrangements are made for-carrying off the bad or cold air inthe room or rooms thus supplied with fresh air from without.

It will readily be perceived that myinventiou,

in its several bearings, is susceptible of modidrawing; but

What I claim, and desire to secure by Let- -fications,v and I do not,therefore, limit myself to the precise form of stove shown in the tersPatent, is as follows:

1. The combination of the reservoir W, for

the-reception of cool air, with the heatingchamber M, and hot-air flues0, p, and T, substantially as and for the purpose shown and described.

2. The combination of the triangular hot-air flue T, with thesurrounding smoke-conductin'g heating-flues E, F', and G, formed by the:plates 1), b and 12 having perforations at w y, substantially in themanner and for the purpose specified. I

3. In combination with the triangular hotair flue-T, surrounded by thesmoke-conductling heating-flues E, F, and G, the valves or registers. U00, arranged and operating substantial-ly as and for-the purpose.specified.

In testimonythat I claim the foregoing as my own, I have hereuntoaffixed' my signature in presence of two witnesses.
